BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 455,731, dated July 14, 189.1.

Application filed February 18, 1891. Serial No. 381,923. (No model.)

To coll whom it may concern: l

Be it known that I, CYRUS E. BATES, acitizen of the United States, residing at Bloomington, McLean county, Illinois, have invented certain new and useful Improvements in Ealing-Presses, of which the following is a specification.

My invention relates to improvements iu baling-presses; and it consists in the peculiar construction and arrangement of parts forming the hopper and feeding device, of which the following is a specification.

In theaccompanyingdrawings,in which like letters and gures of reference indicatelike parts throughout the several views, Figure 1 is a central sectional view of so much of a balingpress as is necessary to illustrate myimprovements, the condensing-hopper being open.v

Fig. 2 is a similar view, the condensing-hopper being closed and the feeding device in its lowest position. Fig. 3 is a view looking in the direction of the arrow from the line y -g/ of Fig. 1. Fig. 4. is a view similar toFig. 2 of a modified form. Fig. 5 lis a detail view of the latch, and Fig. 6 is a view similar toFig. 1 of another modified form.

In the drawings, B indicates the balingchamber, which is of ordinary construction and within which the usual plunger P is caused to reciprocate by any suitablcmechanism connected to a source of power. As shown, the plunger is connected to a crank and crank-shaft by a pitman p.

The hopper H, which is of the condensingtype, is composed of fixed side and end pieces 1 2 and a sliding end piece 3, which is connected with the plunger-operating mechanism so as to be reciprocated with the plunger. As shown, the movable piece 3 is fastened at either side to rods or bars 4.. which slide in grooves in the sides 1. These grooves are of equaldepth with the rods, so that the rods are flush with the sides of the hopper and do not interfere with the passage of material throughthehopper. The barseare connected at their outer ends by a cross-piece 5, and

-through the medium of this cross-piece and a stud or studs 6,-extending upward from the plunger and connected to the cross-piece, the

sliding end of the hopper is caused to reciprocate in unison with the plunger. The studs Gare connected detachably tothe piece 5, so

that thefeeding device and the hopper may be readily disconnected while the plunger remains in motion. This may be accomplished in various ways. For instance, the crosspiece 5, as seen in Figs. l and 3, has hinged to it a latch 7 in th-e form of a bar, which eX- `that when the latch-har is dropped the contact of .the beveled faces of the studs will raise it, the studs will passvunderneath, and the latch-bar will then drop and automatically couple the movable side of the hopper to the plunger.

The feedingdevice F is so constructed that as the-hopper opens to lreceive a fresh charge ot hay or other material it recedes or moves back to a position in which it is entirely out of the way of the attendants. It is, moreover, constructed of few and simple parts and made adjustable, so that it can be readily adapted to different grades and classes of material. In the preferred form an arm 8, which carries the plates or forks 910,is pivotally connected at one end to the slides 4, which carry the movable side of the hopper. A link 13 is pivoted at one end to the upper side of the baling-chamber at a point 14. near the forward limit of the travel of the pivotal end of the arm 8.- r1he other end of this link is pivotally connected to the arm S at a point near its center. The inner fork or plate 9 is fixed to the arm near its outer end and the outer fork is pivoted to the arm at 16. A spring 11 is interposed between the forks to normally keep them apart, their distance apart being limited by their extended rear ends l2 abutting, or in any other suitable way. The link 13 is made adjustable in length by means of a turnbuckle 17 or other adjusting device in order lto vary the depth to which the forks penetrate the baling-chamber.

raised.

The arm 8 is preferably connected to the sliding bars 4 through the medium of a crosspiece 19, to which the arm is attached, and which is provided at its ends with pintles or journals which enter bearings in the bars. y'

A cover 20, which is fixed to the upper edge of the movable part 8 of the hopper at one end and rests upon a support 21 near its other end,serves to keep the hay or other material from interfering with the operation of the arm and link. This cover and the side piece 3 are provided with slots 22, through which the arm projects. As an additional guard to 'keep the material from getting into the slot 22, I proyvide Wing-boards 23, which extend upward from the cover 20upon either side of the slot.

The mechanism so far described operates as follows; As the'hopper is moved to its open condition, as shown in Fig. .1, the arm 8 recedes, carrying the forks or plates away from the mouth of the hopper. IV-hen in this position the hopper is charged with material, and as the plunger is drawn back thehopper closes, partially condensing the material, until the movable side comes flush with the shoulder'18 of the baling-chamber. As this side approaches the shoulder 18, the 'arm 8 descends and forces the material down into the baling-chamber. The parts are so proportioned and the operation so timed that as the plates or forks descend the side 8 comes flush with the shoulder 18 and no obstruction is offered to the passage of the material to the hopper. rEhe fork or plate 10 being pivoted; easily yields should material tend in any Way to bind between it and the stationary'side 2 of the hopper as the forks or plates 9 and 10` descend.

The division-boards E are of the usual form. Then it is desired to insert one of the division-boards, it is placed against the fixed side2 of the hopper, with its lower edge resting upon the` plunger while the hopper is open. IfVhen the hopper closes and the plunger is Withdrawn, thev division-board drops into the baling-chamber, and at the same time an additional chargeof material may beforced down. I am thus enabled to insert the division-board without stopping the machine or interfering with the feeding device, the boards being'put down each time'along With a charge of the material to the bale. The receding or rearV feeding device (shown in Figs. 1 and 2) greatlyfacilitates the insertion of the boards, being one reason Why this form of my invention ispreferable to that shown in Fig. 4, and 'to 'the ordinary feeding devices used in this class of machines.

4Ilihen it is desired to stop the movement of the hopper and the feeder, the latch 7 is The hopper will then be forced open andleft in that condition until the latch is again dropped to automatically engage the moving studs upon the plunger.

' Although I prefer to use the receding feeder shown in Figs. 1 and 2, which moves back with the movable side of the hopper, I sometimesreverse the arrangement of the arm and link of the feeder, as shown in Figs. 4 and 6. In Fig. 4 the arm is connected pivotally to a stationary part of the frame of the press, and the link has its lower end pivoted to a stud extending upward from the plunger, While -its upper end is connected to the arm, as in the previously-described form. In this view I have shown a single plate or fork pivoted to the outer end of the arm and guided by a link 24, which acts as a second arm to give the lower end of the fork a vertical or nearly vertical motion. In this modification the link 13 may of course be pivoted to the sliding bars 4, as in Fig. 1, or to any other reciprocating part of the machine.

The form shown in Fig. G is the same as that shown in Figs. l and f2,"e2gcep`tingfthat the arm 8 ispivotedto thestationary part`14 and the link 13 is placed back ofthe arm and pivotally connected thereto and to the slides 4.

Without limiting myself to the preciseiconstruction and arrangement shown, I claim- 1.
